chore: refactor CI workflow to streamline code checkout process

- Removed the code checkout step from the custom setup action and added it directly in the CI workflow steps for better clarity and control.
- This change ensures that the code is checked out before the build environment is set up, improving the overall workflow execution.

Benefits:
- Enhances the CI process by making the code checkout explicit and easier to manage within the workflow.
